SKF BY-BAQ3809C Flanged Steering Bearing – Four-Point Contact Ball Bearing 40x75/85x16mm

The BY-BAQ3809C is a flanged four-point contact ball bearing engineered specifically for electric power steering (EPS) rack and steering gear applications. Built around a 40×75/85×16 mm envelope, it pairs a solid one-piece inner ring with an integrated outer-ring flange, allowing the bearing to be located axially in the rack housing without spacers, snap rings, or additional machining.The ZV-adjacent EZ designation (as cross-referenced to QJ109EZ) signals a bearing tuned for precise, low-play operation in steering assemblies where axial float translates directly into steering wheel free play and road noise.

The bearing is pre-lubricated and double-shielded (ZZ) , making it a drop-in replacement for worn EPS rack bearings on a range of Ford and Lincoln platforms. Whether you are a steering-system rebuilder sourcing a known cross-reference or a distributor stocking a fast-moving Ford EPS part, the BY-BAQ3809C is specified to restore correct rack function rather than merely “fit the hole.”

Integrated Flange for Axial Location
The outer-ring flange seats against the rack housing shoulder, fixing the bearing axially without separate retaining hardware. In EPS racks, this eliminates a common source of end-play and misalignment during rebuilds.

Four-Point Contact Geometry in a Compact Envelope
The raceway accepts combined radial and bidirectional thrust loads within a single bearing width. For steering rack support positions, this geometry delivers the stiffness of a paired angular contact arrangement without the axial stack height.

Solid One-Piece Inner Ring
Unlike split or two-piece inner rings, the one-piece construction resists deformation under the bidirectional thrust reversals typical of steering inputs. The result is maintained preload and geometry over service life, not just at installation.

ZZ Double Metal Shields
Low-friction metallic shields keep coarse debris out of the raceway while supporting the rotational speeds seen in EPS motor-driven racks. The shielded, pre-lubricated configuration is intended for maintenance-free service life inside the steering assembly.
